Sideline warning mechanics

[Theisey]

Mechanics and Overtime procedures are very similar. No matter where you are, it's bound to be different somewhere else.
OT I can understand. NF allows states the freedom to do how they see fit. I'm ok with that and so should everyone else.

But for a sideline warning, why the flag? The first one is a nothing. It's just a warning of what may come. The signal (S15) alone is enought for letting everyone in the house know what happened. If anything, it may keep the annoucer busy looking up what it means.
Personally, I think it has a lot to do with the ego of who is in charge and the "we'll do it my way" attitude.
Count me in for a no flag on the first warning (and hopefully only warning needed).
